JaiKai Posted February 24, 2019 Report Share Posted February 24, 2019 Having serious issues with my 300zx tt and the link G4+ Its a complete new engine build so the engine has never run prior to this ecu being installed. I have Nismo 740cc injectors installed and timing done but she wont start. I do not know anything about mapping so all i need at this stage is getting her idling. I've set the Injector dead times based on setting i found and also tried various settings for the master fuel but i feel she is over fueling. I confirm this when i pull the fuel relay and crank her to burn off any left over fuel and occasionally she starts. Does anyone know of a 300zx with a link ecu and nismo 740cc injectors i can compare maps with ? Otherwise i'm now lost. Quote Link to comment Share on other sites More sharing options...
Rossobianconero Posted February 24, 2019 Report Share Posted February 24, 2019 post your rom to see if we found something odd, and a logger cranking aswell. If it had to much fuel to crank thats a easy fix. Regards Quote Link to comment Share on other sites More sharing options...
ClintBHP Posted February 24, 2019 Report Share Posted February 24, 2019 You injectors are double the size of the original, halve the value in your 'master fuel' setting and go from there: Quote Link to comment Share on other sites More sharing options...
